The invention relates to an
Internet of Things data uncertainty measurement, prediction and
outlier-removing method based on the
Gaussian process. The method is a
dynamical system method of estimating and collecting the standard deviation of
Internet of Things perception sensor measurement errors and combining the
Gaussian process modeling theory with autoregression model representations; prediction values and uncertainty measurement of
observation data effective time sequence data are given, whether the data are missing values or
outlier data is judged according to the information, and data supplement is correspondingly carried out. The method is a non-parameterized probability prediction method. Due to the fact that
training set learning has the feature of tracing
system dynamic states, judgment, early-warning and data supplement can be carried out on data exception and data missing phenomena in time according to the prediction value uncertainty and the sensor calibration standard deviation, the prediction error is small, and the accuracy is high.
The Internet of Things data uncertainty measurement, prediction and
outlier-removing method is used for controlling the quality of
Internet of Things automatic
observation data, and can ensure accuracy of collected data.
